How do I manage my clammy hands while I'm knitting?

I have the same type of problem. I sweat no matter the climate, which sucks, because I am a photographer. Sweat+Clean Lens= Dirty, Sticky Lens.
I have found that if I use medical latex gloves, then cover those with the medical cotten gloves, no sweat can get through to what I am doing, and I can hold on to things easier. Sure, it sucks when you take the things off, but I would suggest doing that in privet, or near someone you wish to make sick.

Here’s a straw that may be graspable. A long time ago, I worked for a man who had a similar problem. He went to a pharmacist who, being old school, knew how to compound many things. He made a liquid (water white and similar viscosity to water) that my boss would put on his hands and the sweating decreased a lot. It wasn’t as if the skin was coated with anything. Perhaps there are still some compounding pharmacists in your area.

Knit cotton, if it’s too hot for wool. Cotton was made for summer knitting.

I do a lot of knitting year round and often have the same problem. Things that have worked for me is a little baby powder or corn starch rubbed on the hands to keep them dry. Or sometimes just rinsing my hands in cool water and drying well works. Another thing that is most effective is to have a small fan. And one more thing that sounds weird but does work is a cold wet towel laid across the back of your neck.

Man I know what you mean. Seems like the only thing that works for me is frequent hand washing.

A towel by you side works. Wipe your hands on it as you need to. You really don’t want to work lotions or powder into your needlework.

Wool is not really warmer than cotton on your hands, but it can be warming your lap up too much. That can be warming the rest of you up, too. If that’s the case, you can drape your work onto something else instead of your lap: a TV tray, the arm of the couch or chair you’re sitting in, a coffee table if you sit on the floor, the kitchen table.
